GigAlarm is a multipurpose alarm / reminder program, capable of running files and playing multimedia files (including MP3s) to notify you of events. But GigAlarm is capable of many other alarm actions including changing the background wallpaper, syncing the system clock via the internet (using RFC-868 or RFC-2030), shutting down / restarting / logging off Windows, scheduled hibernation resume, wave file playing (random or selected) and program / file running (also random or selected). GigAlarm is a multithreaded programs (i.e. it takes advantage of multi-processor/core and hyper threaded machines) and can schedule thousands of different events. Alarms can be programmed to auto-repeat by a time offset (such as every 5 hours or even a random time) or a set time after boot. Alarm repeats can also be set to miss certain days.

Various views are supported, including next alarms in order, deleted alarms, all alarms, a large view mode for across the room viewing and a calendar preview mode. The preview mode even shows the Window-Up Time, World Times and your daily bio-rhythm!
